Soft Magnetic Alloys Demand Sspeed Up In New Energy Vehicle
Soft magnetic materials are mainly used in the three application fields of charging piles in the new energy vehicle sector, on-board AC/DC chargers, and on-board DC/DC converters. The AC/DC charger can output the input alternating current in the form of direct current, which is a device for charging the power battery; the DC/DC converter can convert high-voltage small current into low-voltage large current, which is used to supply power to other electronic devices on the vehicle. In addition, soft magnetic materials are also used in other parts of the car, such as keyless systems, audio speakers, reversing images, etc. The most widely used soft magnetic materials in the field of charging piles are high-frequency PFC inductors made of soft magnetic powder cores, which can store energy and filter. Gap core technology can effectively avoid defects such as excessive magnetic flux density amplitude, high loss and high temperature when the traditional converter is working, reduce air gap loss, and improve conversion efficiency, service life, safety and reliability. Soft magnetic materials may realize wireless dynamic charging mode for new energy vehicles. As wireless chargers are more widely used in new energy vehicles and require more power, this will become another incremental market for alloy soft magnets in the future. Compared with traditional charging, wireless charging is safe and flexible, especially in the dynamic charging mode, which can charge electric vehicles in real time during driving, and can better meet consumers’ requirements for electric vehicle battery life.
Soft Magnetic Alloys Demand Sspeed Up In New Energy Vehicle
The trend of high voltage is a new point of view in the demand for metal soft magnetic powder cores. Metal soft magnetic powder cores are mainly used for OBC inductors of EV models, with a single-vehicle consumption of 0.7kg, and boost inductors and OBC inductors of PHEV models, with a single-vehicle consumption of 3.3kg. According to the current sales ratio of pure electric vehicles and hybrid vehicles, the average amount of metal soft magnetic powder cores for each new energy vehicle is about 1.22kg, corresponding to the global demand for metal soft magnetic powder cores for new energy vehicles in 2022 is 13,200 tons. In order to deal with the short battery life and slow charging of EV models, the industry has proposed a solution to increase the voltage from 400V to 800V. To achieve this solution, a boost inductor needs to be installed on the DC/DC converter. This will increase the single-vehicle consumption of EV models from the original 0.7kg to about 2.7kg, an increase rate of about 300%. Based on the average unit consumption of 2.82kg per new energy vehicle in 2025, the global soft magnetic demand for new energy vehicles will reach 66,000 tons, with a CAGR of 71.0% from 2022 to 2025.
The increase in the number of new energy vehicles has brought about an increase in the demand for charging piles, and the number of charging piles in the European and American markets is expected to increase. According to the statistics of the China Charging Alliance, the total number of public + private charging piles in China was about 450,000 in 2017, and reached 5.21 million in 2022, with a CAGR of 63.2% from 2017 to 2022. The construction pace of charging piles will be accelerated in 2022, and the total number of charging piles will increase by 99% year-on-year. %, the increase ratio of vehicle piles is 2.65:1. In February 2023, the Ministry of Industry and Information Technology issued the “Notice on Organizing and Carrying out the Pilot Work of Comprehensive Electric Vehicles in the Public Domain”. Strive to achieve 1:1, and the proportion of public parking areas in China that are not equipped with charging piles is still 32.20%, both of which have a certain room for decline. Globally, in 2021, the ratio of new energy vehicle piles in Europe will be as high as 12.3:1, and that in the United States will be as high as 15.9:1. In August 2022, the United States enacted the “Inflation Reduction Act” (IRA) to expand tax credits Cap exemption: The plan is to expand the tax credit limit for a single charging station from $30,000 to $100,000 starting in 2023. Subsidy policies have been strengthened, and charging piles are expected to usher in an accelerated construction period. Soft Magnetic Alloys In New Energy Vehicle
DC fast charging piles expand the demand for metal soft magnetic powder cores, and the global charging pile soft magnetic market may reach 1.7 billion yuan in 2025. DC fast charging is the conversion of three-phase alternating current through AC/DC modules into high-voltage direct current that can directly charge lithium batteries of electric vehicles. The core components are modules such as AC/DC converters, APFCs, and rectifiers. According to industry production data, the current dosage of metal soft magnetic powder core per kw is 0.1kg. With the continuous improvement of the cruising range of electric vehicles, the market puts forward higher demands on the speed of energy replenishment, coupled with the upgrade of fast charging technology by OEMs, the penetration rate of high-voltage fast charging piles has gradually increased. At present, mass production of 100kw charging piles in the industry has begun, and it is expected to be upgraded to 300-400kw in the future. It is conservatively assumed that due to technology upgrades, the unit consumption of metal soft magnetic powder cores per kW will drop from 0.1kg to 0.06kg in the future, and the consumption of metal soft magnetic powder cores for each charging pile will still increase significantly from the original 2kg to 18kg. Assuming that the penetration rate of 300-400kw charging piles accounts for 40% of DC charging piles by 2025, the average unit consumption of each charging pile is 10.8kg. Based on this calculation, the global demand for metal soft magnetic powder cores in 2025 is estimated to be about 34,900 tons, with a CAGR of 191% from 2022 to 2025.
